Abstract
The utility model relates to a phrenic muscle pacing and respiration apparatus, which is an improvement on an extracorporeal midriff muscle pacemaker. The phrenic muscle pacing and respiration apparatus, which belongs to a physiotherapy and function rehabilitation medical apparatus, is characterized in that an integrated circuit produces pulse series which have therapeutic functions when a manual switch or an automatic switch is pressed; The pulse series, which are shaped and amplified, respectively act on phrenic nerve motor points (the 1/2-1/3 site on the lower part of the outer edge of the sternocleidomastoideus muscle) on the left and the right both sides of the patient through a therapeutic electrode to stimulate the phrenic nerves to cause the phrenic muscle to start pacing. The utility model has the advantages of steady output pulse waveshape, automatically replacing alternating current and direct current power supplies, capability of being developed to microprocessor control, etc.
Description
This utility model is a kind of improvement to external diaphragm pacemaker, is the Medical Instruments of a kind of physiotherapy and functional rehabilitation.
A kind of external diaphragm pacemaker of Chinese patent application number 87208778.6 applications, it is characterized in that by manual or fast number automatically, under the control of trigger impulse network circuit, power amplification circuit is exported two-way boost pulse through skin electrode 1/2-1/3 place to the bilateral chest lock mamillary process muscle outer edge, stimulate phrenic nerves and cause diaphragm pacing, improve respiratory function.Its shortcoming is the only fixing output of (1) diaphragm pacing number of times 9 times/minute, is that the working life of relay is short with relay tip control, and machine error is big, and fault rate height, contact easily produce spark, and the parameter shakiness is disturbed big; (2) its circuit final stage is the high-frequency impulse self-excited oscillator output amplifier of holding concurrently, and directly output electrode is subject to patient's body surface parameter feedback, causes oscillating condition to change the frequency of oscillation instability; (3) Shu Chu pulse not synchronously and the intensity indication because of there not being built-in conditioned circuit, does not have very big randomness so export pulse, causes diaphragm pacing asynchronous and cause disordered breathing; (4) no alternating current-direct current automatic switching circuit when alternating current power supply is interrupted suddenly, can't continue treatment.
In order to overcome above-mentioned shortcoming, this utility model is to provide a kind of improved external diaphragm pacing device.
Task of the present utility model is finished like this, press manual or automatic switch, produce the train of pulse of treatment usefulness by integrated circuit, train of pulse through shaping, amplification acts on phrenic nerves motor point, the patient left and right sides (1/2-1/3 place under the chest lock mamillary process muscle outer edge) respectively by therapeutic electrode, stimulate phrenic nerves and cause diaphragm pacing, improve the physiology of respiration function, promote the patient respiratory functional rehabilitation.
